Very nice. If you want to narcotize these for stacking, I've had very good results with a Magnesium Sulfate solution (Epsom Salts). Once you have located the specimen, put a large drop of the solution at one end of the slide cover slip and draw it in by putting slips of toilet paper on the other end to draw the solution across the slide._________________Michael Reese Much FRMS EMS Bethlehem, Pennsylvania, USA
